At one time I was able to lookup friends and classmates online for free. Have not done so for quite a long time and seems like you have to pay to get phone numbers. Anything free anymore?

All depends on where you live. In Toronto we go on line with 411 to get phone numbers.

I have already tried that site and you wind up having to pay, not free.

Limited info like phone numbers is free on that site. I use it frequently.

For one thing, I took the upgrade to Win 10. I even tried to get my own phone number and it did not work.

I use this site, seems to work for me.

I have even tried to look myself up and it does not work. I give up. Done
